User Manual
eter. The user may now invoke a Start command in order to start acquiring data. In this case the
driver will automatically configure the TDC the card using the parameters set by the user and run
the data acquisition. As configuring the TDC card takes up to 1 second, a second way of starting
the data acquisition is implemented, as well: by using the Reconfigure the TDC card is configured
and then ready for data acquisition (state Configured in Fig. XXX). A Start command will now start
data acquisition instantaneously. This path is intended for users who need a low latency between
an intended start and the real start of the data acquisition.
The command Pause will stop the data acquisition but leave the TDC card fully configured. Being
in the Pause-state a Continue will immediately restart the data acquisition. If the user intends to
change some of the TDC's parameters or to clear the buffers a Stop command is necessary taking
the driver back to the state Configured. If the parameters remain unchanged, a Start will immediately restart the data acquisition. By changing parameters the driver returns to the Not Configured state, a restart from that state will take longer as he TDC card needs to be reconfigured before the data acquisition is invoked.
The current state can be queried with the getState() method.
